Kale (Brassica oleracea L. var. acephala DC) leaf water loss as affected by genotype and bagging.

The aim of this study was to determine the effect of enclosing kale leaves in PE-bags on leaf weight loss, water loss rate and chlorophyll index in two kale genotypes (cv. ‘Red Russian and ‘Konavle 2’ which is a Croatian local population). The experiment was consisted of six replications with three leaves per treatment at room temperature (22oC ; 50% RH) for five days. Non-bagged leaves of both genotypes, after 5 days, had more than 50%, while bagged leaves had only 17% of water loss. Water loss rate was higher in ‘Red Russian’ than in “Konavle 2’ only in non-bagged leaves. Enclosing leaves in plastic bags reduced the rate of leaf water loss resulting in increased shelf life of kale leaves.
